Design electronics for instrumented sports balls and player tags from architecture through volume production. Responsibilities include power, charging, radio, antenna, sensing, schematic design, PCB layout in Altium, EMC, validation, bring-up, documentation, design reviews, manufacturing handover, and component lifecycle management. The role requires hands-on development of compact, low-power, mixed-signal embedded products operating under severe space, weight, power, impact, and manufacturability constraints.
